|As a guide for flat ground calculate the decking areas in square metres and multiply * £60.
If the decking is on a slope add £25 per sqm. Add £100 for railings.
Use the calculator to estimate the totals cost.
Ex 1. flat ground 5m*6m. Calculate 5*6*60
Ex 2. decking edge on flat ground cutting into a slope. 5m*6m*85+25
Ex 3. 2 level decking 5m*3m * 60 flat + 4m*3m * 85 + 25
